/**
	Use classpath mapping to determine the source of the specified class
	file.  (Like the Unix which command for executables).
	

    This command maps the entire classpath and prints all of the occurrences
    of the class.  If you just want to find the first occurrence in the
    classpath (the one that will be used by Java) you can also get it by
    printing the URL of the resource. e.g.:
	


    
        print( getResource("/com/foo/MyClass.class") );
		// Same as...
        // System.out.println(
        //    getClass().getResourceAsStream("/com/foo/MyClass.class" ) );
    
	

	Note: This is all a lie! This command is broken and only reports the
	currently first occurence! To be fixed!
